application filed March 3, 1925.

This application is a division of my original application S. No. 690,861, filed February 5, 1924:.

My original application is concerned with certain so-called centrifugal units which, being employed as an avenue for the movement of a flowing stream of any fluid, have the effect of setting the stream into rapid rotation, and, as av consequence of such rotation, bringing about a centrifugal separation of the heavier from the lighter constituents of the fluid. The subject matter of the present application is a component part of said unit, namely, a multiply tuyred ring through which the fluid moves from the outer to the inner side and by which the fluid is so directed as to occasion its rapid rotation within the tuyre ring. rlhe presentinvention is concerned with a particularly advantageous form or construction of the multiply tuyred ring and will be fully understood on reference to the accompanying drawings in which Fig. l is a side elevation of a tuyre ring embodying the present invention; Fig. 2 is a cross-section thereof on the line 2-2 of Fig. l; Fig. 8 is a similar cross-sectional view illustrating a ring of slightly modified form; Figs. l and 5 are obverse and reverse perspective views of one of the staves, many of which are used in making up the complete ring of Fig. 2; Figs. 6 and 7 are like views of one of the staves composing the ring of Fig. 3; Fig. 8 is an enlarged sectional detail taken from Fig. 2; Fig. 9 is a like View taken from Fig. 8, and Fig. 10 illustrates a modification of the stave constructure shown in Figs. 2 and 8.

The tuyre ring as a whole comprises a circumferential series of inwardly directed operatively overlapping slit-like tangential tuyres, all having the same direction. The tuyres proper are marked e. They are formed by the spaces between the tangentially positioned tuyre blades or staves CZ.

ce The latter are fastened one to the other in series and thus the ring is completed.

When iiuid under pressure is supplied to a space external to the tu'y-re ring it passes tangentially into the same in the form of many thin films or streams. Obviously, these Patent No. 1,539,435. Serial No. 12,899.

Divided and this have a common direction, and in consequence of this direction and the velocity of iiuid movement there is immediately set up within the ring a rapid rotation of the whole Huid content of the ring. As explained in'my sig".

original application, all particles contained by the fluid and which are heavier than the same are therefore centrifugally projected upon the inner' side of the staves or blades and are held in that position by centrifugal force until they are longitudinally disturbed or moved by a longitudinal displacing force, and such force is availed of to deliver the heavier substances to one of the ends of the tuyere ring, from which point it is discharged, while the purilied iiuid is permitted tol escape along the axis of the ring.

For reasons of convenience, durability and economy the staves or blades of the tuyre ring are made in the novel manner and form herein shown. In its simplest form a ring component or blade or stave is preferably a metal casting and is thinly triangular in cross-section. In spacing them apart to provide the tuyere openings, each stave is provided with integral spacing projections or lands and those-of one space intert with the next stave. The lands are positioned upon either the inner or outer sides of the stave as contrasted in Figs. 8 and l0, as may best accord with the method adopted in moulding them in quantities.

Figs. 2, l, 5 and 8 represent staves of the thinly triangular cross-sectional shape above mentioned. Each such stave presents a fiat inner side or face cl2. Its pattern may therefore be laid flat on a mould-board. The triangular cross-section of the body portion d3 Vof the stave Z best appears in each of the staves shown in Fig. 8. On the opposite side Z4 of each stave are three projecting ribs or lands d5, Z5 vand d6. The end lands d5 are identical. ReferringV to the other side of the stave, the inner face cl2 is provided at its ends with notches or sinks Z7 that receive projecting lugs Z8 of the lands These staves are thus interlocked against relative transverse and longitudinal movement. The face of the middle land Z6 is flat. It merely approaches or bears against the flat face of the next- 1G@ stave. The middle land of each stave contains two bolt or rivet holes du, and, as shown, each interlitting blade is secured to the next blade or stave by means of a short bolt or rivet d1. The heads of the bolts or rivets are countersunk in the inner face Z2 of 'the stave so as not to form an obstruction thereon. In each case the hole at one end of the stave is drilled perpendicularly to the surface of that edge, this being for convenience in machining the parts, and this is the only machine Work proper that need be performed on the stave. The ends of the stave are merely ground flat, usually after the ring is assembled by means of the connecting bolts or rivets.

Where certain substances are to be handled, it is desirable that the entering streams or films shall be instantly deflected. For such uses the staves d may be made in the interlocking shapes shown in Figs. 6, and 9. Their inner faces Zu are curved and their backs correspondingly formed with the curved lands CX12. rllhus the tuyere openings e, see F ig. 8, are made almost truly tangential to the inner periphery of the ring as a Whole, and in each case the substance flowing through the tuyere e meets and is suddenly deflected by the instanding portion or edge Z13 of the nent blade.

`The method of interlocking the stares by means ofthe employed lands is only varied in the shapes thereof. The method of bolting or riveting the staves together is not changed from that before described.

rlhe instances of the occurrence of the lands on the inner faces of the staves are common, and such lands are Well represented in Fig. 10, Where the obverse lands are marked (Z13. rlhey are not changed in function and do not require further description.

In all forms of this invention the operating pressures on the inner and outer sides of the staves -or blades is substantially the same. lTherefore a pressure resisting ring structure is not required and it becomes possible to build up the complete ring from simple cast metal staves which are self interlocking and with each stave fastened to the next by a single and relatively small device. rl`he structure thus becomes of such low cost as to permit its very general and extended use.

Having thus described my invention, I claim as new and Ydesire to secure by Letters Patent- 1. The herein described multiply tuyred self-completed ring component comprising a cast metal blade having end and intermediate spacing and self interlocking lands and provided with fastener holes in each intermediate land.

2. The herein described multiply tuyred ring, comprising a circumferential series of angularly positioned blades all having the same direction, abruptly shouldered interlock saacing lands integral with each blade and JOSEPH MARTIN SCHUTZ.
